Apl. Prof. Dr. Doris Vollmer
Doris Vollmer studied physics at the University of Bielefeld, the ETH Zurich (Switzerland) and the University of Utrecht (The Netherlands). She completed her PhD at the University of Basel in physical chemistry. For her habilitation (2000) she moved to Mainz and joined the group of Prof. Manfred Schmidt. From 2001-2002 she worked at the Institute of Physics and Astronomy at the University of Edinburgh (Great Britain) as a Marie Curie Fellowship. In 2002 she joined the group of Hans-Jürgen Butt and became group leader in May 2003. In 2015 she obtained a professorship at the Physics Department of the Johannes Gutenberg University Mainz. Currently, she is the coordinator of the Innovative Training Network (ITN) on Lubricant Impregnated Slippery Surfaces (LubISS) (http://www.lubiss.eu/).
Wetting and capillary flow
We aim to explore the potential of capillary flow to understand and tune wetting of simple and multicomponent liquids close to rough and porous substrates. Here, the wetting and flow properties are determined by the interplay of surface energies, morphology and elasticity. We combine synthesis of model structures, analysis of microscopic and macroscopic features with complementary experimental techniques and modeling by mean-field descriptions. Confocal microscopy forms our main characterization technique. The gained information is complemented by interference and high-speed video microscopy, normal adhesion and friction force measurements and COMSOL simulations. We envision to push forward our fundamental understanding of wetting and capillary flow and to use these insights to explore applications of environmental concern. In particular we are interested in lubrication, imbibition, superhydrophobicity, anti-icing, anti-(bio)fouling and flow through granular media.
